Okay, so let me start by saying that acidmods is a great community. I think its great that everything is pretty much open source when it comes to projects. But, I have some questions about programming RF Code it C. Which is it:
1. When you have a pin check for input, compare that to a 1, if yes, you switch it so it outputs a 1, then back to an input, wait for so long, then check for an input again, etc
2. Or is it you have a pin check for input, compare that to a 1, if yes, you switch it so it sinks the pin to a ground by outputting a 0, continue this for so long, have the pin stop grounding itself by outputting a 1 for maybe 5ms, then checking for input, etc
So which method is it and why?
Also, does the matrix or cg/cg2 naturally read high or low?
Thanks.
